How Do You Clean Copper with Citric Acid?

You can clean copper with citric acid by creating a paste or solution and applying it to the copper surface. Here's a breakdown of the method:

Cleaning Copper Using Citric Acid

Here's how to effectively clean copper using citric acid:

Citric Acid Paste: Mix citric acid powder with a small amount of water and a drop of dish soap (optional, but helps the paste adhere) to form a paste-like consistency. The dish soap helps the paste stick to the copper surface.
Citric Acid Solution: Alternatively, dissolve citric acid powder in water. A stronger solution will clean more effectively, but start with a weaker solution to avoid potential damage.

Paste: Spread a thin, even layer of the citric acid paste over the copper surface you want to clean.
Solution: Submerge the copper item in the citric acid solution or apply the solution with a cloth or sponge.

Allow the citric acid to sit on the copper for approximately 5-10 minutes. The duration depends on the level of tarnish.

Wipe off the paste or solution with a damp cloth or sponge.
Rinse the copper thoroughly with clean water to remove any remaining citric acid.

Dry the copper item completely with a soft cloth.
For a more polished look, you can use a copper polish after cleaning and drying.

Test in an Inconspicuous Area: Before cleaning the entire item, test the citric acid on a small, hidden area to ensure it doesn't damage the copper.
Protective Gear: Consider wearing gloves to protect your skin from the citric acid.
Ventilation: Ensure good ventilation when using citric acid, especially when creating a solution.
Avoid Abrasives: Do not use abrasive sponges or cleaners, as they can scratch the copper.
Stubborn Tarnishing: For heavily tarnished copper, you may need to repeat the cleaning process or use a stronger citric acid solution.
Not for Lacquered Copper: This method is not suitable for copper items that have a protective lacquer coating, as it can damage the coating.
